To all whom 'it may concern Be it known that l, .FRANK Crrms'rnnson, o citizen of the United States, residing et Dunton, Leno; Island, in the county of Queens and Stute of New York, have invented certeim new and useful improve ments in Rooiings, of which the following is e specification.

This invention relates to rooting and has for its object the provision of Ineens whereby composition rooting may he, leid in an economical manner end, -when laid, will present en attractive appearance. The inven tion also seelrs to provide roofing which moy be carried through the valleys of e roof Without the eniployement ci metallic structure. @ther objects of the invention will appear incidentally in. the course of the following description.

i The invention is illustrated in. the eccompanying drawings, in whichM Figure l is o plan view of e portion of a roof having composition shingle strips leid thereon in accordance with my invention;

Fig. 2 is e section.v on the line 2-2 of Fig. l;

Fig. 8 is e detail plen View of e portion of e roofing strip showing the manner of cuttin lthe seine.

lt y invention hes special reference to roofing which is composed. of asphalt and felt orfsimilcr flexible Waterproof materiel 'endis furnished in strips rolled for treneportetio'n. Heretofore, these composition strips havel hed their edges parallel, and narrow notches With parallel Wells have heen formed at intervals along,r one edge so that, Whenlthe strips were leid in overlapped relation upon e building end treneversely thereto, a. similarity in eppesrence to ordinary; shingle ,roofing Wes obtained. Such stripsl however', have been objectionable for they reason that the corners of thc strips would curl after the strips had been4 in position. 'for e short time 21nd,'moreoverl', the inished roof frequentl had e liet and unattractive appearance. n o strong Wind,

`theerposed portion of the shingle strip l' will turn up and, will not return 'to normal position but will move, with the wind, knocking upon the root" timbers in e, noisy rnenner. My improvement overcomes these objections. in carrying out my invention, l provide sheet rooting in. e strip l having parallel longitudinal edges 2 and when the strip is to he epplied seine along its center hy forming ents 3' therein disposed et .right ongles Vso yes to intersect ond thereby produce tvv'o strips liev- .ing serre-ted edges. thereby eliminated. it the ends of the strip, the diagonal cuts 3 ere continned to the side edges of the strip, es shown. et 4l., end the points may loe cut-oil, indicated et 5. The smell portion. cnt troni the ends of the strip in this manner is placed et the corner ot the roei" with its edges elining with the edges out" the roof, this portion oeing indicated oy the ninnerel 6 in Fig. l., The strips having the serrated edges ere then successively leid. upon the rootx strncture on diagonal lines, es shown et 7, and the points or projections 8 formed by the serretions or intersecting diegonel cuts nre caused to overlep the upper and side edges of the portion 6 end the previously leid strips respeqtively, the overleppinp)- rangement being shown clearly et 9 in Fig. 2. The edges l of the strips will he caused to coincide 1with the lower edge oi" the huild-` ing or roei structure, as shown clearly in Fige l, and the edges ci the projections 8 will successively register or eline with the edges of previously laid projections so that the completed root` evil-present lines entending transversely' end-longitodinell of the LIS root free of notches end Wllthereoy evoid curling,v and also presente very ettrective .eppeerencewj @Wing the diagonal er-4 rang-ement ol the successive strips., the ends thereof, more remote from the ,lower ofthe roei structure, may loe carried di re'ctly through the valleys of the roof withu out the employment of any rnetellic fou-.ndetlon so that the cost of the finished roof will be materially reduced ond the time reopii ed `for iinishing the seme minimized. it nl -he understood? oli course, thet each succes sive strip is nztilcd to the root struc e, es indicated at 10, and the nails or techs l0 will lpreferably he so arranged that c on teck will he covered by the projecting po of en overlapping' strip. My improved roo.` inc@ strips may he rolled for trensportetion end storage and zney be readily cnt the place of use. To facilite-te the of the strips, lines tney he merlred thereon to guide' the roofer in cutting the strips and precision in the .ii/crit nfillloe therehy sured. i

to roof, hisse-t the l/lleste of materiel is f Eli? fl lll? lalong the roof produeihg a unique slrable appearance.

strip whenl in place exposes of a shingle and the strip Having thus described what is claimed as new'isc The combination of a plurality of superposed roofing strips, the said Astrips being `the invention,

ugvand down in the wind and4 rovided each with one serrated edge and eing laid diagonally onv a roof whereby the serrated edge of eachI strip Will overlap the straight edge portion of a previously laid 15 strip, and the serrated edges Will deine right angular projections having their sides `extending in parallel lines transversely and longitudinally of the roof.

In testimony whereof I aliix my signature.
